SPECIFICATION forming part of Letters Patent No. 610,937, dated September 20, 1898.

' Applicatioi; filed September 2,1897. Serial No. 650,321. (No modeL) To all whom it may concern:

Be it known that I, FRANK E. BUN DY, a citizen of the United States, residing at Elmira, in the county of Ohemung and State of New York, have invented certain new and useful Improvements in AcetyleneGas Generators, of which the following is a specification.

My invention relates to improvements in the manner of delivering the water to the carbid within the generating-chambers, more especially of acetylene-lamps and the like, wherein the gas is taken directly from the generating chamber and delivered to the burner as rapidly as generated.

In the prevailing modes of water-delivery the bulk of the carbid soon becomes incased with or embedded in the resultant lime deposit, which deposit impedes the chemical reaction and causes a spasmodic generation of the gas, which in turn produces a jumping at the burner.

The object of my invention is to obviate this trouble by providing for a more even distribution of the water throughout the mass of the carbid, and I accomplish this object by placing the carbid, either broken up or in specially-formed cakes, in layers of a desirable thickness in the generating-chamber with some absorbent material--such as blotting-paper, absorbent cloth, &c.-extending between the layers from the place of waterdelivery, as illustrated in the accompanying drawings, in which- Figure 1 represents a partial section of a generating-chamber, showing my preferred manner of carrying out the invention; Fig. 2, a section through a sealed box in which a charge of carbid prepared in this manner may be put up and kept ready to slip into the generating-chamber at any time; Figs. 3 and 4, side and top elevations showing how the absorbent material is built up, and Fig. 5 a modification showing a simple mode of carrying the invention into effect.

Similar letters refer to similar parts throu ghout the several views.

A represents a section of a generatingchamber in which is located a carbid-receptacle B. At the center of this receptacle is a perforated stand-pipe O, which receives water from the source of water-supply through the opening at its top. Around the standpipe is a vertical cylinderD of the absorbent material, from which horizontal disks or layers E of the same, material extend out into the broken carbid or between the cakes of the carbid, breaking the mass of the carbid up into shallow layers, as shown. As the water is fed into the stand-pipe it issues through the perforations and strikes the absorbent material, through which it is carried out into the body of the carbid, which at once takes up the moisture and gives off the gas, the gas escaping upwardly around the outer periphcries of the absorbent layers. As the lime resulting from the decomposition is formed in necessarily thin deposits between these ab sorbent layers and the fresh carbid, it cannot oppose much resistance to the passage of the water to suchfresh carbid, and the generation of gas will be found to continue steadily and without fluctuation, giving a steady flame at the burner.

In Fig. 2 I have shown a charge of carbid suitable for the generator illustrated as I propose to put it up for the convenience of the consumer. F represents a strong paper bag, of cylindrical form and of proper diameter, within which are placed the absorbent cylinder and its radiating disks, the lowermost of which disks is of the same diameter of the bag. The carbid is then packed in and around the disks, a cork or plug G being placed in the top of the cylinder to keep the carbid out both while packing the bag and afterward. When the carbid is filled in to the level of the top disk, the top of the bag is folded down and the charge placed in a suitable box H, which is made of some material impervious to moisture,the cover of which is sealed. The charges so put up may be sold and kept for an indefinite time ready for instant use. WVhen the charge is to be used, the box is broken open, and the charge removed and slipped into place in the carbid-receptacle, as shown in Fig. 1, the plug being removed and the top of the bag being torn off. The charge so put up is smaller in diameter than the receptacle, in order that as decomposition takes place the enlarging bulk of the lime deposit can be accommodated by the expansion of the bag. The upper layers of the absorbent material, it will be noticed, are made smaller in diameter than the lowermost one, in order that the gas may be given ample space through which to rise to the top of the generating-chamber.

The absorbent disks and cylinder may be molded out of pulp or fiber in one integral piece or the cylinder made separate and the disks slipped on as the carbid is filled in.

' Also the cylinder may be dispensed with and disks only be used, as shown in Fig. 5,where the carbid and disks E have been filled in and built up directly within the carbid-receptacle without the use of a previously-prepared charge.

Having thus described my invention in its different phases, and without intending to limit myself to the precise mode or manner as herein described of carrying it into effect, what I claim as my invention, and desire to secure by Letters Patent, is-

1. In a generating-chamber, the combination of alternate layers of carbid and an absorbent material built up around a central stand-pipe, through perforations in which water is delivered to the several absorbent layers substantially as described.

2. A charge of carbid for a generatingcha'mber built up in layers around a central cylinder of absorbent material with absorbent material extending out from said cylinder between the layers, the Whole being inclosed in a moisture-proof envelop, substantially as described.

In testimony whereof I have afiixed my signature in presence of two Witnesses.
